Green philosophy ....

If a tree falls in a forest and no one is around to hear it, does it make a sound? 

Not a day for scientific or philosophical debate on this question as we stepped over many fallen trees on our hike on the Appalachian Trail today. The entire trail is 3,500kms long and runs from Georgia through to Maine. Hikers that attempt the whole trail usually take about 6 months, carry all their gear and camp along the trail.

I'm taking a much more leisurely approach ... 4 days of hiking, about 15kms a day. Then back to a hotel with a comfortable bed, hot shower, WiFi and red wine.
